LBT OSU/RC Observing Notes Date: 2016 Jan 03 (UT) Observers: Rick Pogge and Jake Turner (at Tucson Remote Facility) Support: Olga Kuhn (On call; in remote room for a few hours) TelOps: David Gonzalez Summary: Sky is clear at sunset. Start of the night the sky is clear and sky is photometric (0.8" seeing). We started with LBC. LBC blue is not fixed, so we are only using LBC red. Acquired and observed UM_CEW_CMT/c2013x1 in non-sidereal mode, clear and no clouds (0.8" seeing and stable). At UT 02:14, switched to MODS. Acquired and observed OSU_ASASSN15ts, clear and stead 1.2" seeing. Good spectra and can see emission lines. Acquired and observed ND_mls/mls in bino mode with LBC red and MODS, clear and steady seeing is 0.6" (photometric). Good spectra (can see emission lines) and images. AT UT 06:30, switched back to LBC. We observed 13 targets (see below) all in clear to light cirrus and steady seeing around 1". Only had weather problems on OSU_monitor/N4826 and reran the script after clouds moved over. All images of the galaxies look good! We encountered several errors: for the focus of OSU_monitor/N3344 and OSU_monitor/N3627 we received the popup box error: "command rejected since another is running!". While taking the images for Obs OSU_monitor/N4449 the far right panel (didn't contain the galaxy) appeared as the read-out was smeared in the long axis direction. To fix both these errors David had to kill and restart the LBC software.

The other panels don't seem to be affected (the one with the galaxy). UT 11:39 Olga recommended we power cycle the detector as this error was seen before. We power cycled, however, that didn't fix the problem. David killed the software twice, and it started working again. UT 11:47 Focus OSU_monitor/N4736 UT 11:55 Obs OSU_monitor/N4736 (6x100secs; 10 minutes) (heavy cirrus, 1-1.1" seeing) Can't see many stars or structure in the galaxy. UT 12:09 Re-running Obs OSU_monitor/N4736 There was pretty thick cirrus over the FOV on the last images. Looks a lot better since less clouds are over the FOV. UT 12:23 Focus OSU_monitor/N4826 UT 12:28 Obs OSU_monitor/N4826 (9x200seconds: 30 minutes) (light cirrus, 1-1.1" seeing) UT 12:58 Astronomical Twilight UT 13:04 Night is over and we are closed up.
